Toyota shows robotic leg brace to help paralyzed people walk
Toyota is introducing a wearable robotic leg brace designed to help partially paralyzed people walk.
The Welwalk WW-1000 system is made up of a motorized mechanical frame that fits on a person's leg from the knee down. The patients can practice walking wearing the robotic device on a special treadmill that can support their weight.
Toyota Motor Corp. demonstrated the equipment for reporters at its Tokyo headquarters on Wednesday.
One hundred such systems will be rented to medical facilities in Japan later this year, Toyota said. The service entails a one-time initial charge of 1 million yen ($9,000) and a 350,000 yen ($3,200) monthly fee.
The gadget is designed to be worn on one leg at a time for patients severely paralyzed on one side of the body due to a stroke or other ailments, Eiichi Saito, a medical doctor and executive vice president at Fujita Health University, explained.
The university joined with Toyota in developing the device.
A person demonstrating it strapped the brace to her thigh, knee, ankle and foot and then showed how it is used to practice walking on the treadmill. Her body was supported from above by a harness and the motor helped to bend and straighten her knee. Sensors in the device can monitor the walking and adjust quickly to help out. Medical staff control the system through a touch panel screen.
